Abstract
The utility model discloses a plastic gear with a metal outer layer. The plastic gear comprises a gear body, outer teeth, a metal sheet, the metal layer and a gear center. The metal sheet is located in the gear body and is connected with the gear center. The metal layer is located on the outer surface layer of the gear body, the gear body is made of nylon materials and the gear center is made of metal materials. Through the method, the friction coefficient of the plastic gear can be reduced, heating phenomena can be reduced, and the gear can have broader application scope under the condition of lowering the cost of the gear.
Description
Technical field
The utility model relates to a kind of plastic gear of mechanical field, particularly relates to a kind of plastic gear with metal outer.
Background technique
Plastic gear has been a kind of conventional component of machine aborning.The gear that the plastics of take in gear are in the past material, although cost ratio metal gear has in the past reduced.But because the friction factor of gear is larger, in not only making to produce, waste a large amount of energy, but also the heating bringing because of friction causes mechanical damage.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of plastic gear with metal outer, the friction factor of plastic gear can be reduced, and minimizing fever phenomenon, can make gear in the situation that reducing costs, and makes the application area of gear more extensive.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of plastic gear with metal outer, gear body, external tooth, tinsel, metal layer and the tooth heart; Described tinsel is positioned at gear body interior, and described tinsel is connected with the tooth heart, and metal layer is positioned at gear body external layer, and gear body is nylon material, and the tooth heart is metallic material.
In preferred embodiment of the utility model, stating a kind of plastic gear with metal outer is spur gear
In preferred embodiment of the utility model, described tinsel and the tooth heart are formed in one.
In preferred embodiment of the utility model, described a kind of modulus with the plastic gear of metal outer is 2 ~ 4.
In preferred embodiment of the utility model, described metal layer thickness is 2 ~ 5mm.
The beneficial effects of the utility model are: the utility model connects as one the tinsel adding in plastic gear and the tooth heart, and plates metal layer at the external layer of plastic gear.Not only can reduce the friction subsurface coefficient of gear, also can extend the life-span of gear.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is a kind of structural representation with plastic gear one preferred embodiment of metal outer of the utility model.
In accompanying drawing, the mark of each parts is as follows: 1, gear body; 2, external tooth; 3, tinsel; 4, metal layer; 5, the tooth heart.
Embodiment
Below the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment provides following technological scheme.
In one embodiment, a kind of plastic gear with metal outer, comprising: gear body 1, external tooth 2, tinsel 3, metal layer 4 and the tooth heart 5.Described tinsel 4 is positioned at gear body 1 inside, and described tinsel 4 is connected with the tooth heart 5, and metal layer 4 is positioned at gear body 1 external layer, and gear body 1 is nylon material, and the tooth heart 5 is metallic material.
Be different from prior art, in one embodiment, preferably, described a kind of plastic gear with metal outer is spur gear, and described a kind of modulus with the plastic gear of metal outer is 2 ~ 4, is preferably 3.
Preferably, described tinsel and the tooth heart are formed in one, and such design not only can be protected the tooth heart 5, can also make plastic gear more durable, strengthen practicability.
Preferably, described metal layer 4 thickness are 2 ~ 5mm, can play the effect that reduces friction factor.
The utility model adds the method for metal layer 4 by top layer, the friction factor of plastic gear is reduced, and reduces fever phenomenon, can make gear in the situation that reducing costs, and makes the application area of gear more extensive.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
Claims (5)
